Abstract (en)

[origin: EP2523298A1] A method for controlling transfer of electrical power in island mode in an arrangement comprising a converter and a load connected to the converter through a filter. The method comprises determining voltage reference components for one or more frequency components of an output voltage of the converter. An effect of a load current is compensated for by forming one or more voltage feedforward terms on the basis of the load current and using the feedforward terms to adjust the voltage reference components. Control reference components for one or more of the frequency components are formed on the basis of the voltage reference components, and a control reference is formed on the basis of the control reference components. The output voltage of the converter is controlled on the basis of the control reference.
